On Wednesday night, Milk Gallery and designers Sam Shipley and Jeff Halmos of Shipley & Halmos rallied New York's most stylish and weather-resistant for the launch of photographer Aaron Stern's Everyone Must Be Announced, a collection in which the experience of concertgoers, rather than artists, is the primary subject. Zoe Kravitz, Penn Badgley, and Annie Clark of St. Vincent enjoyed DJ sets from Alexa Chung, The Like's Tennessee Thomas, and Andrew Wyatt of Miike Snow, with cocktails courtesy of Red Bull and Ketel One.
